This document describes various settings to make IGEL OS more secure. In general, the more of these settings you apply, the better device security will be. However, it is up to you to strike a balance between security and enabling your users to do their work. Some settings may even be inappropriate for your use case, e.g. if you use Bluetooth peripherals, it does not make sense to disable Bluetooth.
In order to configure multiple devices, put the relevant settings into a Universal Management Suite (UMS) master profile, which you can assign to any number of devices. For more information, see Master Profiles.
